Note: When forming the past participle in Spanish, the infinitive ending is dropped, and ido/ado is added depending on the type of verb. It can be an ‘ar’, ‘er’ or ‘ir’ verb.

For example:

Hablar (to speak) - hablado

Comer (to eat) - comido

Vivir (to see) - vivido

However, this rule does not apply to irregular past participle verbs. Each verb has their own special ending. Here are some examples:

• Abrir (to open) - abierto
• Cubrir (to cover) - cubierto
• Decir (to say/tell) - dicho
• Disolver(se) (to dissolve) - disuelto
• Escribir (to write) - escrito
• Hacer (to do/make) - hecho
• Imprimir (to print) - impreso
• Morir (to die) - muerto
• Poner (to put) - puesto
• Resolver (to resolve) - resuelto
• Romper (to break) - roto
• Ver (to see) - visto
• Volver (to return) - vuelto
• Componer (to mend/compose) - compuesto
• Describir (to describe) - descrito
• Descubrir (to find/discover) - descubierto
• Deshacer (to undo) - deshecho
• Devolver (to return something) - desvuelto
• Disponer (to dispose) - dispuesto
• Imponer (to impose) - impuesto
• Oponer (se) (to oppose) - opuesto
• Predecir (to predict) - predicho
• Proponer (to propose) - propuesto
• Reponer (se) (to recover) - revuelto
• Suponer (to suppose) - supuesto
